Dealing with IE8 false dns errors

I notice that IE (version 8 in my case) puts up a bogus DNS error. The internet connected and I can get to pages on the site in question.

The link is:
http://rails-trial-90.1steasy.net/angl/countries/timezone/tz22.htm

It should redirect to:
http://rails-trial-90.1steasy.net/bear/articles/tz22

Anyone else have to work around the issue?
